LOOSE LEAF BINDER Filed April 25, 1935 2 Sheets-Sheet l INVENTOR llllllllllllllllllllllllll ll! 2 M1 7 QM ATTORNEY Patented Aug. 6, 1935 UNITED STATES PATENT OFFICE Application April 25,

4 Claims.

The object of this invention is to provide a new and improved form of binder for loose leaves, which leaves withrthis binder can be bound into book form.

Another object of this invention is to provide a binder in which the leaves can be assembled independent of the covers of the book, and then inserted into the covers by an endwise movement, thereby locking the leaves in place in the book.

These and other objects of the invention will be illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the drawings:

Figure 1 is a bottom plan View of the bound book.

Figure 2 is a section through the book at some intermediate point such as is indicated by the line 2.21-23; on Figure 3.

Figure 3 is a side elevation of the book with the covers raised, showing the loose leaves bound in the book and the spring take-up device.

Figure 4 is a section on the line 433-411: of Figure 1.

Figure 5 is a top plan view of one of the loose leaves.

Figure 6 is a top plan view of the block and leaves assembled therewith removed from the frame and covers.

In the drawings like reference numerals indicate like parts.

In the drawings reference numeral I indicates the front cover of the book and 2 indicates the back cover of the book. These covers are hinged to a rigid sheet metal frame 3 comprising a conveX back l, parallel sides 5 and 6, which sides are connected to the concave back by flanges l and 8, which flanges extend outwardly and form with the convex back, on the inside of the frame, recesses 9 and it The binder comprises a block ll, preferably made of wood, having a flat face l2 in front and a convex back lit. On the flat front face is provided a metal plate M, the outer edges of which are bent inwardly to form channels l5 and H5. The lower edge of this plate is bent forwardly, as indicated at IT, to form a flange on which rests a blade spring l8. On this blade spring is provided a plate i9, that is wide enough to be engaged in the channels 15 and IS, on which rests the back edges of the loose leaves 20.

Each of these loose leaves is cut with a V- shaped recess, one recess on each of the two opposite edges thereof, as shown in Figure 5, and as are indicated by the numerals 25 and 26. These 1935, Serial No. 18,169

recesses are adapted to engage with the inturned edges of the channels l5 and I6. By these recesses on the back of each sheet is formed tongues 27 and 23 that engage in the channels l5 and i5. On top of the assembled loose leaves is placed another plate or bar 2!, which is also engaged in the channels l5 and l t. This bar rests directly on the pages and serves to hold them in engagement wit-h the channels. The spring 18 takes up the extra or lost space in the binder, and yields as more leaves are inserted from time to time.

With the loose leaves assembled in the channels l5 and I6, and the top plate 2| placed thereon, the whole assembly is slid endwise into the frame 3 to which the covers are attached. The outer edges of the block I I engage in the recesses formed between the flanges T and 8 and the convex back 4-, and is positively held therein. On the back 4 is carried a pin 22 which engages in a recess in the end of the block, which limits the endwise movement of the block and holds the block positively in its proper position in the frame so that it cannot slide out in the wrong direction. This pin, however, does not interfere with the removal of the block and the leaves assembled thereon by a reverse movement, or a movement in the right direction.

When it is desired to insert new pages, the assembly of the block and pages are removed from the frame, after which the bar 2| is removed and more pages are added. The bar 2| is then replaced and the assembly of the block and pages is again inserted in the rigid frame.

I claim:

1. In a binder for books, the combination of a rigid hollow frame having short parallel sides running the length thereof, each of said sides having an outturned flange at the rear thereof, a convex back connecting said flanges and rigid therewith, boards hinged to the forward edges of said parallel sides, said flanges and convex back forming on the inside thereof a concave runway having a groove on each side thereof, a block, binding devices carried on the forward face of said block, said block having edges that are adapted to engage in the grooves of said runway by an endwise movement, said binding devices being held in place by said parallel sides.

2. In a binder for books, the combination of a rigid hollow frame having short parallel sides running the length thereof, each of said sides having an outturned flange at the rear thereof, a convex back connecting said flanges and rigid therewith, boards hinged tothe forward edges of said parallel sides, said flanges and convex 55 back forming on the inside thereof a concave runway having a groove on each side thereof, a block, binding devices carried on the forward face of said block, said devices comprising a plate having the ends thereof bent into the form of channels and having a flange bent on one side thereof, said channels being adapted to receive tongues formed on the loose leaves, a loose bar placed on top of said loose leaves with its ends engaging in said channels.

3. In a binder for books, the combination of a rigid hollow frame having short parallel sides running the length thereof, each of said sides having an outturned flange at the rear thereof, a convex back connecting said flanges and rigid therewith, boards hinged to the forward edges of said parallel sides, said flanges and convex back' forming on the inside thereof a concave runway' having a groove on each side thereof, a block, binding devices carried on the forward face of said block, said devices comprising a plate having the ends thereof bent into the form of channels and having a flange bent on one side thereof, said channels being adapted to receive tongues formed on the loose leaves, a loose bar placed on top of said loose leaves with its ends engaging in said channels, a leaf spring bearing on the flange of said plate, a bar carried on the forward face of said spring, the ends of said spring and bar engaging in said channel, the back edge of the leaves being held between the two bars.

l. In a binder for books, the combination of a rigid hollow frame having short parallel sides running the length thereof, each of said sides having an outturned flange at the rear thereof, a convex back connecting said flanges and rigid therewith, boards hinged to the forward edges of said parallel sides, said flanges and convex back forming on the inside thereof a concave runway .havinga groove on each side thereof, a block,

binding devices carried on the forward face of said block, said block having edges that are adapted to engage in the grooves of said runway by an endwise movement, said binding devices being held in place by said parallel sides, a pin on the frame engaging with one end of said block for the purpose of holding it in place.
